Implements detection of unexpected successes and expected failures. Both
classes are represented in the TAP output as 'not ok', unexpected
successes with '# FIXED' metadata and expected failures as '# TODO'.
This brings C++ tests to feature parity with Python-based ones when it
comes to expected failures and unexpected successes.
This allows tools like `prove` to operate on our test-suite, allowing us
to do things like run recently-failing tests first, randomising test
order, and fancier reporting options.
Changes made:
- TAP output always goes to STDOUT, never to STDERR
- Skipped tests signaled as `ok 1 # skip` as per standard
- Expected failures signaled as `not ok 1 # TODO` as per standard
- `.prove` added to .gitignore
- Many files were missing an explicit cmake.h include. Some were not including
it at all. Now it's used almost everywhere.
(cherry picked from commit 82ae86979c497e6d1d0c6b2b5a55aa379ec82c98)
- Removed unnecessary definitions of max() and min(), replaced existent calls
with std::max(). Precursor to Bugfix #887.
